Calories Burned During Exercise
Estimate how many calories you burn during physical activity based on your weight, the activity intensity (MET value), and duration. This helps with fitness tracking, meal planning, and understanding energy expenditure.
Formula
The formula is Calories = MET × weight(kg) × time(hours). MET (Metabolic Equivalent of Task) represents the energy cost of an activity. Running at 8 MET for 30 min at 70 kg burns approximately 280 kcal.
Worked example
A 70 kg person cycling at a moderate pace (8 MET) for 30 minutes burns about 280 kilocalories. Increase intensity to 11 MET (vigorous running) and the same 30 minutes burns about 385 kcal.
Practical guidance
Finding the right MET value
Common MET values: walking = 3-4, cycling = 6-8, running = 8-12, swimming = 5-10, weight training = 3-6. Higher intensity means higher MET. Use online MET tables to find values for specific activities.
Calories are estimates, not exact science
Actual calorie burn varies with fitness level, body composition, age, temperature, and form. This calculator provides an estimate based on the standard formula. Use it for planning, not for precise medical diet prescriptions.
